AUTOMOBILE RADIATOR.

Application filed March a, 1928. Serial a. 258,834.

This invention relates to improvements in automobile radiators, especially radiators of the sectional water tube construction; Wherein the core is composed of vertical sections comprising groups of water tubes imbedded in closely spaced horizontal fin plates, and the sections are attached at the ends to the upper and lower radiator tanks. In many cases, it was found that such radiators are damaged by vibration, the core being shaken apart at the joints.

In this invention the main objects are to provide a radiator having a core which is reinforced so that it will withstand the vibration of the vehicle and will not vibrate of itself; to provide means for stiffening and reinforcing the construction of core now used; to provide means for interconnecting the sections of the core without obstructing the flow of the air through the core; and to provide means for stiffening the core transversely and in the cross-sectional planes without materially increasing the weight.

An illustrative embodiment of this invention is shown in the accompanying drawings in which:

Figure 1 is a front elevation of the radiator.

Figure 2 is a side view of a fragment of one of the radiator sections.

Figure 3 is a plan section taken on the line 33 of Figure 2.

Figure 4 is a fragmental perspective View of one of the re-inforcing bars.

Referring to the drawings, the top radiator tank 1 and the bottom radiator tank 2 are rigidly mounted in spaced relation in the side frame members 3; and the core, or heat transferring element, is composed of a plurality of vertical sections 4 communicating with said tanks at their ends.

The sect-ions 4 are each composed of a group 'of water tubes 5 which extend through and are bound together by the closely spaced fin plates 6. At corresponding intervals in each section, along the length thereof, are provided plates 7, Figure 2, which are slightly longer than the plates 6, and which extend beyond the ends of the same at the front and at the back of the core. The medial portions of the sections are interconnected by means of the bars 8. The bars extend across the core, and are secured to the ends of the corresponding plates 7, in each section. In the constructions shown, the bars are U-shaped in section and fit over the ends of the plates 7, and the bars are secured to each plate by means of two bolts 9.

The reinforcing bars serve to stiffen the core by connecting the sections together. IVithout the reinforcements, the sections, owing to their narrow width in proportion to the length between the end supports, have a tendency to vibrate, and'this tendency is, of course, eliminated by interconnecting the sections by means of the bars 8. It is manifest that, by providing the bars at both the front and back of the radiator, the cross section of the core is eifectually strengthened. Also, by using somewhat heavier material for the lengthened plates 7 and the reinforcing members 8, avery strong core can be provided without materially increasing the weight, nor increasing the resistance to the flow of the air through the core.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims. v

I claim:

1. In an automobile radiator having top and bottom header tanks, and having a core consisting of a plurality of thin walled cooling sections connecting the tanks, each .section having a fin plate incorporated in its structure, and a bar extending across the core between the tanks, said bar being secured to each of said fin plates for strengthening the core and preventing vibration.

2. In an automobile radiator, a tubular sectional core having sections each consisting of a group of vertical tubes imbedded in 'spaced'horizontal fin plates, a U-shaped bar extending across the core, said bar embracing a fin plate in each section and secured thereto,

In an automobile radiator, a tubular sectional core, having sections each consisting of a group'of vertical water tubes imbedded in spaced horizontal fin plates, and bars extending across the front of the coreand across the rear of the core in the medial portions thereof, said bars being secured to a fin plate in each section.
